Things You'll Need:
-
Step 1
Using a measuring tape, figure out the dimensions of the room you are putting the humidifier in. Then look for machines that work in a larger size room. Individual room humidifiers tend to cover a smaller area then stated on the box.
-
Step 2
A cool air humidifier will cool a room a degree or two. A warm air humidifier will heat a room a degree or two. Choose the one that is appropriate for your climate conditions.
-
Step 3
Humidifiers will come with some degree of noise unless you plan to purchase a high end unit. The water draining into the unit from the water chamber will also create a sudden noise. Decide what level of noise you are willing to deal with and then look for units that are quiet or exceptionally quiet.
-
Step 4
All humidifiers require you to replace filters--which is a necessary, added cost. Best to purchase a couple of replacement filters at the same time that you buy the unit itself. Instructions included in the unit will explain how often filters require changing.
-
Step 5
Make sure that your humidifier manufacturer states that it does not produce "white dust." In lower end units this can be a by-product of transmitting moisture into the air. Adding moisture with dust isn't on most people's list of desired features, especially for those with dust allergies.
-
Step 6
Most single room humidifiers will raise the humidity a small amount but this is usually sufficient to dispel any nasal or sleeping issues. If the humidifier states that it will raise the humidifier in a room by over 35 percent, then make sure that the unit comes with a built-in humidistat. This will measure the moisture in the air and turn off when it reaches the desired level.
-
Step 7
Check to see if the humidifier you are interested in is dishwasher safe. This will making cleaning a breeze.
